Bar in a bathroom (4)
I believe the answer is:
soap
'bar in a bathroom' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for soap that I've seen before include "TV series of cleansing sort" , "Day-to-day TV series" , "made in a bar?" , "Serialised drama" , ". . . . opera, sentimentalised radio or tv series" .)
